Harassment by owner - Pizza Perfect Broadacres

I placed a telephonic order with Pizza Perfect on Fri eve 13/02/2015. Order was R239.00. When the order was delivered, I paid via debit card. The delivery person said he was having problems with the machine. The transaction went through my account - I received my normal sms notification advising the funds having left my account. An hour later, the owner of the store felt it fit to arrive at my estate and requested to be let in. Which I did. When he arrived at my door not alone, but with two other guys, he demanded to know why I had not paid because he has received a rejection from his bank. When I showed my sms to him he insisted that I swipe my card again to which I refused. I said to him that I will go to his store in the morning should the transaction be reversed. The reversal came back into my account at 08:00 the following morning after which I went to pay. The owner then harassed me on Saturday AFTERNOON on numerous occasions (cell phone records can prove the number of times he called). When told that the bill was paid & that he should check with his manager BEFORE calling, as well as owing an apology he got extremely abusive over the phone. I WILL NEVER BE BACK!!
